Waist exercising device

ABSTRACT

A waist exercising device has a housing case holding a transmission motor that drives a gear box via a decelerating machine. The gear box is connected with a shaft that leads a guiding portion to perform a circular motion. The user&#39;s waist is then guided to perform a swaying motion.

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to a waist exercising device and, in particular,to a device that guides a person to perform a waist swaying motion.

2. Related Art

There are many exercising machines on the market. As far as shaping thebody is concerned, such machines include waist bending, hip swaying,chest extending, weight lifting, and jogging. In particular, thetraditional hula hoop requires the user to continuously twirl the waistin order to rotate the hoop. Therefore, it is claimed to be able toachieve body-shaping effects. Moreover, this exercise is widely acceptedby people at all ages because of its smooth and beautiful twirlingmotion.

Even though the traditional hula hoop has many advantages and featuresthat cannot be matched by various bodybuilding equipments and ispromoted by many people, it still has the following problems:

1. It is not easy to play with the hula hoop. In addition to having somebasic skills and talent, the user has to accept failures in thebeginning and practice perseveringly before he/she can learn the trickand master the exercise. It is thus extremely difficult for a personlacking of confidence or courage. Therefore, it often cannot achieve theexpectation.

2. The diameter of a normal hula hoop is fixed. Therefore, it may not besuitable for everybody. For example, children and adults have to usehula hoops of different sizes.

3. Generally speaking, one sways the waist to twirl the hula hoop. Tostart the twirling from the static state of the hula hoop, the user hasto exert a larger twirling force. This is most difficult and dangerousfor senior people because it may result in injuries to the waist.

4. The user has to concentrate on playing the hula hoop. Any distractionmay let the user to start all over again. Therefore, the user is notallowed to do or take care of other works.

In view of the foregoing, it is thus imperative to provide a solutionthat can simultaneously solve these problems.

SUMMARY OF THE INVENTION

An objective of the invention is to provide a waist exercising devicethat actively guides its user's waist to perform a swaying motion.

To achieve the above objective, the invention has a housing case holdinga transmission motor. The transmission motor drives an axle via adecelerating machine. The axle in turn drives a driving gear. Each sideof the driving gear is connected with a driven gear. Each driven gear isprovided with a connecting shaft at a corresponding position on its topsurface. Each link rod is pivotally connected to both ends of aconnecting bar. A rod base is vertically disposed between the link rods.A shaft is provided in the rod base. An adjusting device is used toadjust the height of the shaft inside the rod base. A guiding part forthe user to sit on is provided at the top of the shaft.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detaileddescription, which proceeds with reference to the accompanying drawings,wherein the same references relate to the same elements.

Please refer to FIGS. 1 to 3. The waist exercising device in thisembodiment has the following structure. A housing case 11 is disposed ona base 1 for holding a transmission motor 2. The transmission motor 2drives an axle 211 into rotation via a decelerating machine 21. The axle211 is pivotally connected to the decelerating machine 21 and protrudesfrom the top of the housing case 11. A connecting part 12 protrudes fromthe front end of the base 1 upward and approaches the human body. Thetop of the connecting part 12 is provided with a control panel 13electrically connected with a circuit board for controlling theoperation of the transmission motor 2 inside the housing case 11. Theaxle 211 driven by the transmission motor 2 is disposed with a drivinggear 4 transmitting in the axial direction on the housing case 11. Thedriving gear 4 drives a driven gear 5 on each side of the axialtransmission into rotations that are in phase. The housing case 11 isprovided with a protection shell 14 for protecting the driving gear 4and the driven gears 5. Each driven gear 5 is provided with a link rod51 at the corresponding position on its surface. A connecting bar 6 ispivotally installed on each of the two link rods 51 and extends upwardout of the protection shell 14. A rod base 61 is provided above the linkrods 51. The top of the rod base 61 is empty for the installation of aretractable shaft 7. An adjusting device 8 is used to adjust the heightof the shaft 7 relative to the rod base 61. A guiding part 71 forguiding the user's waist to sway is provided at the top of the shaft.

According to the above-mentioned structure, the transmission motor 2provides the driving force. The decelerating machine 21 reduces therotation speed. The power is transmitted via the axle 211 to the drivinggear 4. The rotation direction is controlled by the signal from thecontrol panel 13 and the circuit board 3. Therefore, when the drivinggear 4 rotates, the driven gears 5 on both sides also rotate. In thiscase, the connecting bar 6 connected to the driven gears 5 via the linkrods 51 starts its link motion, making the rod base 61 on the connectingbar perform a circular motion. This in turn makes the shaft 7 fixed inthe rod base 61 and the guiding part 71 thereon perform a circularmotion (FIG. 4). Before a user strides on the guiding part 71, he/shecan use the adjusting device 8 to adjust the height of the shaft 7 inorder to move the guiding part 71 to an appropriate position to sit.FIGS. 5 and 6 show embodiments of different heights according to theuser's bodies. Before exercising, the user first holds the guiding part71 by slightly squeezing both sides with both legs. Afterwards, the usersets the operation mode using the control panel 13, and then starts theoperation of the device. Since the user has used both legs to hold theguiding part 71, his/her waist is then undergoing a circular motion withthe device, achieving the same effects as playing with a hula hoop.

Although the invention has been described with reference to specificembodiments, this description is not meant to be construed in a limitingsense. Various modifications of the disclosed embodiments, as well asalternative embodiments, will be apparent to persons skilled in the art.It is, therefore, contemplated that the appended claims will cover allmodifications that fall within the true scope of the invention.
